Is there a math mode accent giving an inverted breve? I have tried \stackrel{frown}{x}, but the alignment and spacing are all wrong when compared to \breve{x}.

Using Psirus's idea:

\usepackage[T3,T1]{fontenc}
\DeclareSymbolFont{tipa}{T3}{cmr}{m}{n}
\DeclareMathAccent{\invbreve}{\mathalpha}{tipa}{16}

\begin{document}
$\invbreve{x}$
\end{document}

enter image description here

One has to load fontenc and specify the T3 encoding; if T1 is not desired, say \usepackage[T3,OT1]{fontenc} so as to get OT1 as the default encoding.

Check out tables 171, 173, 175 and 176 of »The Comprehensive LaTeX Symbol List«. Note that you have to load the corresponding package (given in the table caption) to make the respective command work.

Thanks; this solution works, too, but I can only accept one answer and chose egreg's answer because the resulting symbol looks better to me. – Federico Poloni Jan 15 '12 at 13:34
Personally, I had good success with \wideparen from the MnSymbol package (table 173). – thecommexokid Feb 16 '12 at 7:02
